ART OF MAKING PL-UMBERS TACKS.

SPECIFICATION forming part of Letters Patent No. 297,797,'dated April 29, 1884.

Application filed December 20, 1883. (N model.) I

To all whom it may concern:

Be it known that I, CHARLES EBERHARD HEIss, a citizen of the United States, and residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and Improved Process for lvlanufacturing Plumbers Tacks, which is fully set forth in the following specification, reference being had to the accompanying drawings, in whicl1- Figure 1 represents a plan view of the prepared strip from which the tacks are to be made; Fig. 2, a section of the same, taken on the line as :r, Fig. 1; Fig. 3, a plan view of a single finished tackcut from the strip; and

Fig 4, a section of the same, taken on the line '0 c, Fig. 3.

My invention relates to a mode of making what are known as plumbers tacks, which are pieces of lead adapted for use to-fasten lead pipes to walls, &c., wherever desired. Heretofore these tacks have been made by casting each one singly in a suitable mold, which is a slow and expensive process for making an article which necessarily ought to be very cheap.

It is the object of my invention to make these articles by a mode which shall be much more inexpensive than the usual process mentioned above.

It consists in first preparing a plain strip of lead of such size that the tacks may be cut therefrom by suitable dies, which will not only cut off the tack in the precise form, but will also giveit any finish desired. The lead strip is prepared-by casting, and I prefer to cast it under pressure, as it produces a very supe rior tack when thus cast.

I will proceed to describe in detail my improved process for the manufacture of the articles specified above, and will then point out definitely in the claim the improvement which I believe to be new, and wish to. pro tect by Letters Patent.

In the drawings, A represents a finished tack, which is shown in some ornamentalform, and finished on the outer or upper surface. This is a mere arbitrary matter of choice or taste, as the tack may be perfectly plain in form and finish, so far as its utility is concerned.

At one side the edge a is beveled, as shown in Fig. 4 of the drawings, as usual, to fit the pipe more nearlyagainst which it is placed, and the tack also has two or more holes, a, by which it is fastened to the support along which the pipe runs by means of screws, nails, or any other suitable device fastened through these holes into the support.

In making these tacks a strip of lead, B, is

produced by casting under pressure, .whereby a compact heavy metal is obtained. This strip is of a width corresponding to the width desired for the tack, and has one edge, I), beveled along its length corresponding to the beveled edge of the tack. The strip may be of any length conveniently made in casting. This strip is then cut into tacks in a suitable dropdie press, to which itis fed lengthwise, so as to cut off a tack from the end of the strip,which is fed forward, as shown in dotted lines in Fig. 1 of the drawings. The dies of the press are made so as not only to cut out the tack in the desired form, but also to stamp it, so as to give the surface an ornamental finishsuch, for instance, as shown in Fig.3 of the drawings-and also to punch the holes. Thedies will therefore cut off and make a finish ed tack, which is delivered from the press in condition ready for use.

Ihave not shown and it is not necessary to describe the die-press, for this machine-tool is very generally used for various purposes, and

its construction and operation for the purpose mentioned above will be understood by persons at all familiar with the art without further description here. By this process I am enabled to produce the tacks very cheaply, and

at considerably less cost than by the usual mode .above, so that before stamping the metal is more compact than in the usual mode of male ing the articles, and the tacks stamped from this strip will be very superior to ordinary tacks in strength and durability.

I do not wish to be understood as limiting my process to making the strip by casting under pressure, as very good tacks may be made if the strip is cast in the ordinary way.

5 Having thus described my invention, whatI claim as new, and desire to secure by Letters CHARLES EBEBHARD HEISS. Patent, isv \Vit'nesses:

The herein-described process for the manu- V. C. Commas,

facture of plumbers tacks, the same consist- I A. M. BEST.

ing in first casting a strip of lead of suitable 1c width for the tacks, and then cutting and stamping said strip into tacks by suitable cutting and stamping dies, substantiallyas and for the purposes set forth.
